John is more than just a great HVAC technician… he is honest, dependable, and genuinely cares about doing the job right. In a world where it can be difficult to find people you can truly trust, John stands out. He is responsive, professional, and takes the time to explain everything clearly. I never feel pressured into unnecessary repairs, and his integrity gives me complete confidence in his recommendations. I have used him personally and professionally and I highly recommend John and Core Heating & Air Conditioning to anyone looking for quality work and exceptional service! :-)

John is the person to go when you have any heating issues. He strives do his best at fixing the issue rather than replacing the whole unit. If you are looking for a reliable and honest hvac contractor, look no further.

★★★★★Erin Melcona month agovia Google

We've been having Jon come out for going out on 5 or 6 years now, and will continue to do so until he retires! He is honest and hard-working and takes the time to explain what he's doing. 10 out of 10 every time.
